Over the course of his life, Kerstein has learned that successful businesses are run by 'survivalists", people who can observe and understand what is going on in the 360-degree circle that surrounds them at any given time. That's perspicacity at its best. Unfortunately, Kerstein has had to deal with a gaggle of fools and know-it-alls throughout his career who have inspired the thoughts in I'm Retired: Now I Get Even on subjects such as the following:

• Entrepreneurship: The art of hiring and firing oneself on a regular basis
• Egos and intelligence: The 97% rule
• The twenty-first century's greatest oxymoron: Customer Service
• Sex, lies, and brownnosing: AKA, the truth about climbing the corporate ladder

There was a long list of people Kerstein did not wish to thank for this book, but that didn't seem quite fair because they provided the cannon fodder that makes up most of the chapters. So instead, he thanks them for being stupid, ignorant, egotistical, maniacal, harmful, fatuous, indifferent, macabre, remorseless, and/or all-around jerks.
